CATALYST #3: AUGUST 14 TH, 2013 WRITE CATALYST, NUMBER, DATE, AND ANSWERS IN COMPLETE SENTENCES ON YOUR CATALYST PAPER. Read the excerpt I handed you at the door and then answer the following questions on your Catalyst paper. (Remember: COMPLETE SENTENCES BUT DO NOT WRITE THE QUESTIONS) Susannah describes the brain and brain cells (neurons) as a “symphony” that can be disrupted by only one “dissonant instrument” that will cause a “cacophonous result.” 1. Predict what the words dissonant and cacophonous mean in this context. (Think about her comparison of the brain to a piece of music.) 2. Why do you think Susannah chose the metaphor of a chaotic symphony to describe her mysterious disease’s effects on her body? Use her episode at the beginning of the reading as evidence.

QUICK “BRAIN ON FIRE” DICUSSION  “Brain on Fire” summary  How does this tie into our discussion of Henrietta Lacks and the importance of being Biologically informed?  Do you think that medical issues have been misinterpreted throughout history as something else? Such as?

ANNOUNCEMENTS Class Job Applications Due TODAY : Materials due August 19 th MONDAY Scientific Inquiry Quiz Friday

OBJECTIVES SWBAT formulate a scientific question SWBAT develop a hypothesis SWBAT identify independent and dependent variables SWBAT graph their results in a bar graph SWBAT interpret data in order to form a conclusion

BEACH BALL CHECK FOR UNDERSTANDING As a question comes on the screen, toss the ball to a new person to answer. Expectations: We are all ready for the ball should it be thrown to it. No throwing with intention of hitting anyone.

QUESTION 1 What is the first step in the scientific method? Answer: Make observations

QUESTION 2 What is one example of an observation we have not said before? Answer: Many possibilities

QUESTION 3 What step in the scientific method comes after you form a question? Answer: Make a hypothesis

QUESTION 4 You want to investigate the effects of exercise on weight loss. The question you ask is this: “Does more exercise cause people to lose more weight?” Name a hypothesis (in the correct form) for this investigation. Answer: If a person exercises….then…because….

QUESTION 5 In your experiment, you have four people exercise for different amounts of time each day. You measure how much weight they lose each week. What is the independent variable? Answer: Amount of time they exercise

QUESTION 6 In your experiment, you have four people eat the same food but exercise for different amounts of time each day and one person that does not exercise at all. You measure how much weight they lose each week. What is your control group? Answer: The person who does not exercise

QUESTION 7 Your results are shown below. What is the best conclusion about how more exercise affects weight loss? Answer: I conclude that more exercise causes more weight to be lost (must be a full sentence that answers the question) Exercise/Day Avg. Weight Loss/Week 0 minutes/day 0 pounds 20 minutes/day 0.75 pounds 40 minutes/day 1.2 pounds 60 minutes/day 1.4 pounds

LAB EXPECTATIONS Whole class participation Lab report for a grade Remain seated unless given permission otherwise. When you are listening to the music, remain silent so that you can concentrate on taking your pulse. Music Disclaimer

1. OBSERVATIONS 1.Name some genres of music. 2.Name some emotions that these genres of music evoke. Example: Lady Gaga—Annoyed Are these observations qualitative or quantitative observations? How could you make these observations the opposite?

THIS EXPERIMENT How will grindcore and classical music affect your heart rate? How do we measure a heart rate?  Your pulse  Before we can complete this study, we need to learn how to measure our pulse.

HOW TO TAKE YOUR PULSE

2. QUESTION -Research questions: -What is your opinion of grindcore (a type of rock where people scream and make a lot of noise)? -How does grindcore make you feel? -What is your opinion of classical music? -How does classical music make you feel?

3. FORM A HYPOTHESIS If I listen to grindcore, then my heart rate will __________________________because _______________________. If I listen to classical music, then my heart rate will ______________________ because________________________.

4. EXPERIMENT/DATA COLLECTION: PROCEDURE 1.Count your resting heart rate for 60 seconds and record it in the table. 2. Listen to classical music for 1 minute, count your resting heart rate for 60 seconds and record it in the data table. 3.Listen to grindcore for 1 minute, count your resting heart rate for 60 seconds and record it in the data table. Repeat.

EXPERIMENTAL DESIGN What is the independent variable? What is the dependent variable? What is the control group? What is the constant?

DATA ANALYSIS What type of graph would best show our data? Graphing Components X-axis Y-axis Title Scale

DISCUSSION Individual results Trends as a class? If time—Graph class averages

DRAW A CONCLUSION: REMAINDER Questions to think about…. How did classical music affect your heart rate? How did grindcore music affect your heart rate? Did you see change as you analyzed your data? Does this conclusion support or reject your hypothesis? What would you suggest in a future experiment?

HONORS: COLLEGE LEVEL LAB REPORT Outline of a college freshmen level Biology course lab report Look over and answer the questions What do you notice about the level of detail in this report versus our Heartrate Lab report?
